London, 1894. Juliet
Moreau has built a life for herself—working as a maid, attending church
on Sundays, and trying not to think about the scandal that ruined her
life. After all, no one ever proved the rumors about her father’s
gruesome experiments. But when she learns her father is alive and
continuing his work on a remote tropical island, she is determined to
find out if the accusations were true.

Juliet is accompanied by
the doctor’s handsome young assistant and an enigmatic castaway, who
both attract Juliet for very different reasons. They travel to the
island only to discover the depths of her father’s madness: he has
created animals that have been vivisected to resemble, speak, and behave
as humans. Worse, one of the creatures has turned violent and is
killing the island’s inhabitants. Juliet knows she must end her father’s
dangerous experiments and escape the island, even though her horror is
mixed with her own scientific curiosity. As the island falls into chaos,
she discovers the extent of her father’s genius—and madness—in her own
blood.
